"Buffering" refers to drawing the contents of a window into an offscreen
buffer before copying that buffer to the screen.
Without the buffer, objects are drawn directly into the window on screen,
with noticeable side-effects like "flashing" when the area occupied by an
image or control is erased and the new object is drawn.
With a buffer, this drawing takes place offscreen and is copied in one quick
move to the screen in its finished state, hence no flashing as individual
controls are drawn.
